About POLH

Cytogenetic location: 6p21.1 Genomic coordinates (GRCh38): 6:43,576,185-43,620,523 (from NCBI)

This gene has 3 transcripts (splice variants), 200 orthologues, 5 paralogues and is associated with 3 phenotypes. Ubiquitous expression in lymph node (RPKM 4.3), testis (RPKM 3.5) and 25 other tissues.

Summary

This gene encodes a member of the Y family of specialized DNA polymerases. It copies undamaged DNA with a lower fidelity than Other DNA-directed polymerases. However, it accurately replicates UV-damaged DNA; when thymine dimers are present, this polymerase inserts the complementary nucleotides in the newly synthesized DNA, thereby bypassing the lesion and suppressing the mutagenic effect of UV-induced DNA damage. This polymerase is thought to be involved in hypermutation during immunoglobulin class switch recombination. Mutations in this gene result in XPV, a variant type of xeroderma pigmentosum. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2014]
